40€ picture frame from a local mediamarkt. The PCB appears to be 2 layer with lots of helpful labeling. The microcontroller is a Haier "Hi1018D". Also there is a chip whose marking, "25Q806CP". (see jal2's link for likely datasheet of 2.5v 8MBit spi mem and discussion of Hi1018D).

PCB details:

Notice that on the bottom of the PCB in the picture above that there are two pads for serial (labeled RX, TX)

I guess the chip in picture 3 is labeled "25Q80..." which could be a W25Q80xx, i.e. a SPI flash (8MBit) from Winbond, e.g.
this one
Any idea what the chinese instructions on the PCB bottom mean? Some Info about the HI1018. (jal2)

Carsten Meyer made a mod on a very similar frame with the same chipset. No chip details though.

Chinese translation of PCB text (thank you Geng): "1. remote_control_head J2 (needs to be?) installed with J9 on same side. 2. remote_control_head feet (needs to be) inserted from the other side of J2 imprint. 3. from the edge of the board, the remote_control_head feet (needs to be) 18mm"
